Usage notes[edit]

  • The only non-proscribed use is in the sense of "to give a cost to". Where proper grammar is expected, use cost instead for non-specialized past-tense and past-participle uses such as answering the question "How much did it cost?"
  • Occasionally replaced with noun or verb forms of price, where commonly accepted, as in, "The event's hosting was priced at $1,000,000."
